Set Data
Processing contents
(1) Compares the input value 1 (E1) with the input value 2 (E2), and outputs the result of the comparison to BB1 of the block
memory.
Condition
E1 > (E2 + K)
E1  (E2 + K - HS)
(E2 + K - HS) < E1  (E2 + K)
Operation Error
In the following cases, the error flag (SM0) turns ON and the error code is stored in SD0.
